Safety instructions

The most important safety instructions are summarised in this chapter. It is intended to
supplement the relevant regulations which must be studied by the personnel responsible.
When working in hazardous areas, the safety of personnel and plant depends on
complying with all relevant safety regulations. Assembly and maintenance staff working on
installations therefore have a particular responsibility. The precondition for this is an
accurate knowledge of the applicable regulations and provisions.
When installing and operating the device, the following are to be observed:
•
Read and observe the safety notes in these operating instructions!
•
Ensure that the contents of these operating instructions are fully understood by the
personnel in charge.
•
Use the device in accordance with its intended and approved purpose only.
•
Before installation, make sure that the device is not damaged.
•
The national installation and assembly regulations (e.g. IEC/EN 60079-14) apply.
•
The switching repeater may be installed in Zone 2, Zone 22 or outside the explosion
hazard areas.
•
In the case of operation in Zone 2 or Zone 22, the switching repeater must be fitted in
an enclosure which complies with the requirements of IEC/EN 60079-0.
•
When used in Zone 2 and Zone 22, intrinsically safe devices of Zones 1, 0, 21 and 20
may be connected to the intrinsically safe input circuits.
•
The switching repeater may only be connected to devices which will not be subjected
to voltages higher than AC 253 V (50 Hz).
•
The safe maximum values of the connected field device(s) must correspond to the
values of the data sheet or the EC-type examination certificate.
•
Interconnecting several active devices in an intrinsic safety circuit may result in other
safe maximum values. This could endanger the intrinsic safety!
•
Circuits with type of protection 'Ex i' operated with circuits with other types of
protection can no longer be operated as circuits with type of protection 'Ex i' after that.
•
National safety and accident prevention regulations
•
The device may only be installed and operated if it is in an undamaged, dry and clean
state.
